I subscribe to a website called
PatchingProtocols.com
I pay $10 a month. This is not my website and I make no money from it and neither does Lifeawave. They have many different protocols for all sorts of different conditions that are not limited to simply pain. I use this to get ideas in difficult cases.
It is based on acupuncture points and the nice thing is that the charts are really clear and easy to understand. It is a great learning tool.
If you simply want to learn more about acupunture and see charts and read more go to
YinYangHouse.com This is a free site. It is not related to patches but it teaches how acupuncture works. It is really a great learning tool. They have charts and an explanation of all the points and they show how points are categorized.
